The market value of hoarded food going up only helps Hamas if they are the one managing to do the hoarding - otherwise it actually works against Hamas (if there's another distributor)
Exactly. If Hamas is doing it, it's self-defeating. If Hamas isn't doing it then you're just starving people. Because the point is just starvation, nothing to do with Hamas.
BTW, all orgs (other than the lyin' IDF) says Hamas wasn't stealing significant amounts of aid (nowhere near the 10% claimed). Therefore it's clear starvation was the goal, not targeting funding or Hamas at all.
How is it self-defeating? Hamas is able to continue fighting with the more aid they steal. By stealing aid they also increase the suffering in Gaza thus winning the propaganda war.
Even the IDF now admits it had no evidence of Hamas systematically stealing aid [0].
Yet the talking point - which attempted to justify genocide and never had a shred of evidence - will linger for years. I still meet people who think Saddam did 9/11, or that Afghanistan was connected.
I still meet many people who don't even know a third tower fell in NYC that day. When news media repeats a talking point that long, or ignores evidence that long, it makes a very deep impression on the type of person who takes things at face value a little too much.
